Been having problems with sermon editor? Seems like when I compose a sermon, the screen headings at the top go blank on me, and I cant finish what I started?
Please provide some more details - ideally with screenshots. I haven't seen anything like this reported before.
Although it might be worth restarting Logos to see if that helps.
In addition to restarting Logos, restart your computer. That sounds like something grungy (Not at all a technical term) stuck in RAM.
I always reboot my system from a full power down when weird things like this happen. Cures it the majority of times.
